- subject of the Grand Duke of Baden, residing at 1 Giibenstrasse, Hanover, Germany, have invented certain new and useful Im- 'provements "in Detachable WheeLR-ims, of

the latter,

' the felly,

which the following is a specification.

In the devices hitherto used for automobile wheels and the like in which detachable rims carrying. the rubber tire are fastened onto the telly of thewheel by means of screws, nuts an Wedge-pieces secured by the nut must be turned completely off the bolt in order that the may be taken 01? for the purpose of removing the rim. A considerable amount of time is necessary for taking off the tire and it frequently happens that the nut and the wedge-piece are misplaced-or lost, These dangers are avoided by the present device. In this," the nut is permanently connected with the wedge-piece. By turning the nut the'wedge-piece is drawn out so far that the tire rim can be conveniently taken off orchanged as desired.

In the aocom' anying drawing Figure 1 is a section oi the nut mounted on the Wedge-piece; and Figs. 2' and '3 are eleva tions of the sameat'right angles to each other: Fig. 4 shows the arrangement of the net, the Wedge-piece with the telly and the tire-rim.

- The nut a can be turned in the wedgepiece 6, but is secured by the flanges so that as the nut is turned on the 'boltsha'ft 0 the wedge-piece must follow the movement of the nut. In this arrangement, the nut needonly beturned back a suitable distance wedgepiece' l l 1 l which the wedge piece Specification of :Letters Patent.

The wedge and bolt may be assembled in any desired manner.

6 is secured to the Thus the flange by nut a may comprise opposed lugs which enter opposite sidesof the channel formed in the nut, bent toward each other to form a bearing in which the nut rotates. can be turned on the nut in order to move the ends oi the lugs being thenhe wedge-piece it out of the way of the rim when the latter is taken off. i The wedge-pieoe'may be given any desired form. Similarly, the con-" effected in verb nection with the nut can be one manners without departing from nay-in vention.

I claim as'my invention:

.1 A, device for securing removable tire rims of the character described, comprising a bolt 1 and a nut working thereon together with a wedge piece pivoted on said nut and adapted to engage a riin,- saidwedge piece bein moved into and out of engagement with said rim by the rotation of said nut and swiveling on said nut when cleared of said rim,

so as to (fermit the removal of the latter, as
